A convergent synthesis of carbocyclic sinefungin 2 and its C5 epimer 3 is described. The key features in our synthesis include the use of commercial available L-methionine and readily available (1R, 4S)-4-hydroxy-2-cyclopentenyl acetate as starting materials, cross-metathesis coupling, enzymatic kinetic resolution and Staudinger reduction. The current synthesis is flexible and therefore provides convenient
描述了碳环正弦菌素 2 及其 C5 差向异构体 3 的聚合合成。我们合成的主要特点包括使用市售的 L-甲硫氨酸和现成的 (1R, 4S)-4-羟基-2-环戊烯基乙酸酯作为起始材料、交叉复分解偶联、酶动力学拆分和施陶丁格还原。目前的合成是灵活的,因此可以方便地合成各种用于生物学评价的碳环 SIN 类似物。
